Abstract

(57) [Summary] [Purpose] The objective is to obtain a rotary blade for a hand motor that removes fish scales without compromising commercial value. A rotary blade having a scale in which a plurality of protrusions are provided upright in a radial pattern on the outer peripheral rotating surface with equal width and at equal intervals, and the protrusions are conical in the axial direction.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a rotary blade for picking up a fish scale attached to the shaft of a hand motor.

[0002]

[Prior Art]

 A conventional rotary blade with a scale is provided with a plurality of blades with the same protruding shape on the outer peripheral rotating surface, and the blade edge has the same diameter in the axial direction and the blade is intermittently provided like a saw blade in the axial direction. There is.

[0003]

[Problems to be solved by the device]

 In conventional rotary blades with scales, multiple radially projecting blades with equal width and equal intervals on the outer circumferential surface of rotation are provided intermittently in the axial direction. When removing the scales, the fins are damaged by the interrupted part of the blade, reducing the commercial value. In addition, because the shape of fish is complicated, there are some points that cannot be processed with a blade of the same diameter on the outer peripheral surface of rotation in the axial direction.

[0004]

[Means for Solving the Problems]

 The plurality of blades each have a conical shape that is continuous in the axial direction, and they protrude radially with an equal width and an equal interval to the outer peripheral rotation surface. A shaft mounting hole 3 for connecting to a motor shaft 5 is provided in the shaft 2 provided on the side of the blade edge having a large outer shape. The rotary blade for catching fish scales of the present invention has the above-mentioned configuration.

[0005]

[Action]

 Attach a rotary blade to the hand motor 4 and hold the hand motor 4 with one hand to rotate it. Scales are removed one after another as you move the rotating rotary knife along the body of the fish.

[0006]

[Embodiment 1] In a rotary blade, a plurality of protruding blades 1 each having a similar shape are provided on an outer peripheral rotating surface. The outer diameter of the cutting edge is large on the shaft 2 side and is small on the tip end in a conical shape. The blade 1 forms a continuous blade edge in the axial direction. The shaft 2 has a motor drive shaft mounting hole 3 that is connected to the hand motor shaft 5. Hold the hand motor 4 with one hand and apply a rotating rotary knife along the body of the fish. The scales that have been stripped off one after another and removed by one are repelled in the direction of rotation by the blade 1. On the shaft 2 side, since the distance between the cutting edges is large, large scales of fish can be removed. On the other hand, the tip of the rotary blade is suitable for the scales of small fish and fins because the distance between the blade edges is small. Since the blade edge of the blade 1 is continuous in the axial direction, the blade 1 is not damaged even if it comes into contact with the fin, and thus the scale can be picked up without reducing the commercial value of the fish. Moreover, since the tip has a small blade outer diameter and a curved shape, it is possible to remove scales having complicated shapes.

[0007]

[Effect of the device]

 Fish fins can be removed without damage and from small scales to large scales with one rotor blade. Also, it is possible to deal with a complicated shape.
